My parents pretty much left me to my own devices, and I'm still posting on hacker news. Also, i know people who were forced to learn piano as kids etc. and they are pretty much nowhere as adults. I'd say it's more genetics than anything.
It's genetics, in that genetically you have a probability of being inclined towards whatever subject your Tiger parent is subjecting you to. If that isn't the case, you have a massive misallocation of energy.
I'm against Tiger parenting as a blanket strategy prescribed for all. The fact is that not all parents are equipped to micromanage their children's careers, nor does the physical and emotional abuse involved necessarily lead to best results. The latter is like a shot of steroids - get short term results but lasting damage in all but the hands of experts.
Yeah me too :) I merely applied the measure used by OP to illustrate my point. Agree that there are better metrics for success; as for the measure for procrastination, it's probably spot on ;)
